Introduction
Every year about 120 strong earthquakes with magnitudes of 6 to
6.9 on the Richter scale shake different areas of the United States. But the highest
level of damage is from about 18 major earthquakes that happen
every year with magnitudes of 7 to 7.9 on the Richter scale.

Scientists continuously record
and locate the center of all earthquakes and are trying to find
a pattern that may help them to forecast earthquakes days in
advance.

Many different measuring devices
and equipments are used for this purpose.

Material and instructionsLearn about different
types of earthquakes and how are they measured. You may optionally
build a model of a Seismograph for this project. Also explain
how you can use a seismograph to locate the center of an earthquake.
